使用代码为SharePoint页面上的WebParts设置访问群体

WebParts的访问群体,日文系统中叫[対象ユーザー]

 

通过使用目标访问群体,可以将内容(如列表或库项目、导航链接以及整个 Web 部件 (Web 部件:由标题栏、框架和内容组成的信息模块单元。Web 部件是 Web 部件页的基本结构块。))显示给特定用户组。在希望仅提供与特定用户组相关的信息时,此功能非常有用。例如,可以将 Web 部件添加到法律部门的门户网站,其中包含仅对该部门可见的有效合同列表。

 

要确定目标访问群体,可以使用下列一项或多项:
・SharePoint 组
・通讯组列表
・安全组
・全局访问群体 
     (全局访问群体是基于规则的访问群体,由 SharePoint 管理员维护。)
只要访问群体的名称已知,至少具有参与者权限 (权限:对执行特定操作(例如查看页面、打开项目和创建子网站)的授权。)的任何人都可以指定目标访问群体。
